Ioannis Sadiktsis is a researcher at Stockholm University specializing in the development of advanced analytical techniques for chemical characterization of organic aerosols. His research group focuses on the chemical profiling and toxicological assessment of organic particulate matter. Key areas of interest include the application of coupled chromatographic techniques and high-resolution mass spectrometry for both target and non-target analysis of polycyclic aromatic compounds (PACs). By advancing these methodologies, he aims to enhance the understanding of organic composition in environmental and health-related contexts. Thus, his work is crucial in connecting analytical chemistry with environmental science, particularly concerning the effects of air quality on public health.
